DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

Systems, methods, and apparatus for a ventilating toilet are herein described.

A typical flush toilet is a vitreous, ceramic bowl containing water plus plumbing. FIG. 1 shows a toilet apparatus 100, under an embodiment. FIG. 1 shows a water tank 102 and a base 104. The base comprises a bowl 106, a rim 108, and a siphon 110. A lid 112 is rotatably coupled with rim 108 at point 114. FIG. 1 shows the lid 112 in closed position lying over an opening into the interior of the bowl 106.

The tank 102 dispenses water into the bowl 106. The water in the toilet bowl is under one embodiment connected to a hollow drain pipor siphon 110 shaped like an upside-down U connecting the bowl with a drain. One side of the U channel is arranged as a hollow siphon tube longer than the water in the bowl is high. The siphon tube connects to the drain. The bottom of the upside-down U-shaped drain pipe limits the height of the water in the bowl 106 before it flows down the drain. The water in the bowl acts as a barrier to sewer gas entering and as a receptacle for waste. Sewer gas is vented through a vent pipe attached to the sewer line. When a toilet 100 is flushed, the water should flow into a septic tank or into a sewage system with a sewage treatment plant. The toilet 100 is designed to be rapidly filled with more water once flushed.

Toilets are of course designed to eliminate human waste. It has been designed and redesigned countless times but still presents one major flaw. Flush toilets have a bowl where waste is captured and disposed of with the aid of water. Water floods the bowl and then flushed water pushes the waste and water out of the bowl and into the plumbing below.

The odor from the waste however is left in the bowl and the bathroom housing the toilet. Ventilation fans are typically installed in the ceiling or sometimes in the wall. Ventilation fans help remove the odor from the room. In so doing it actually pulls more odor out of the toilet bowl into the room. A new design directly combines the toilet bowl to a ventilation system. A ventilation fan is placed in the attic and is then attached to the toilet with a piping system. This system vents and all but eliminates the unwelcome odor resulting from use of the bathroom.

Existing toilets may have ports of entry that introduce water into the bowl. Such water is necessary to flush the toilet. These ports are located just under and around the top rim of the toilet. A new design introduces under one embodiment an extra set of ports in addition to the water entry ports. These additional ports are not entry ports but exit ports under an embodiment. The additional ports may comprise vacuum or ventilation ports. They may be placed in many places inside the bowl as long as they do not impede the flow of water and waste in the toilet.

Under an embodiment these ports are coupled together either internally or externally. The connection may lead to a union that attaches to a pipe or hose that is then piped into a wall behind the toilet. The pipe may lead upward through the wall into an attic. Inside the attic the pipe is under one embodiment connected to a ventilation fan. Another pipe may leave the ventilation fan and exit through the roof the way plumbing vents are situated. The odor/scent is then expelled to the outside through the pipe that exits the ventilation fan under one embodiment.

Under an alternative embodiment, the ventilation pipes may also be piped through an exterior wall with the ventilation fan mounted outside said wall. Under yet another embodiment, the ventilation fan may simply expel the odor into the attic. This practice mirrors the operation of many ventilation fans in service that simply transfer air within a bathroom to the attic.

Under an embodiment, the ventilation pipe may run up and along the wall behind or to the side of the toilet inside the bathroom without being placed inside the wall. Multiple toilets may be piped into one central ventilation fan or each toilet may be independently ventilated. The vents may be controlled by a simple light switch which under an embodiment is wired through the wall as any other electrical switch would. Under an embodiment, the electrical switch may be operated with timer switches or any type of automated switch configured to turn on or off when the toilet/bathroom is in use.

FIG. 2A shows a toilet apparatus 100 with lid removed under an embodiment. The apparatus comprises a base 104. The base comprises a bowl 106 and a rim 108. The bowl 106 comprises an exterior surface 122 and an interior surface 124. The rim 108 comprises an upper surface 132, a lower surface 134, an inner surface 138, and an outer surface 140. The bowl further comprises holes or ports 142 that introduce water into the bowl from tank 102 under an embodiment. The surface 150 provides support for the apparatus tank or cistern (not shown) which collects and dispenses water in operation of the toilet.

FIG. 2B shows a cross sectional view of a toilet apparatus rim 108, under an embodiment. FIG. 2B shows an upper surface 132, a lower surface 134, and an inner surface 138 of the rim.

The inner surface 138 of the rim 108 may comprise ventilation ports or air ports under an embodiment. FIG. 3 shows a front view 300 of the rim inner surface 138. FIG. 3 shows air port 302 and air port 304. Each port features a lower portion 314, 316 and an upper portion 310, 312. The lower portion 314, 316 comprises an opening in the inner surface 138 allowing communication of air between an interior of the bowl 106 and an air chamber (FIG. 5, 520) within an interior of the rim 108. The upper portion 310, 312 comprises a hood extending outward and over the lower portion as further described below.

FIG. 4 features a side view of the of ports 302, 304 seen in FIG. 3. The cover portion or the lid 410 extends inwardly from inner surface 138. The lid also extends downwardly over the opening 412. The lid 410 may under one embodiment comprise a spherical shaped hood. The lid 410 covers and protects the opening 412 from entry of materials or substances from above. The lid shields the port while allowing communication of air between an interior of bowl and an air chamber (FIG. 5, 520) within an interior of the rim 108.

FIG. 5 shows air ports 502, 504, 506, 508, Each port allows communication of air between an interior of bowl 106 and an interior air chamber 520 within the rim 108. The air chamber travels along an interior of rim 108 along a first portion from port 508 past port 506 to point 522. The air chamber travels along an interior of rim along a second portion from port 504 past port 502 to point 522. The air chamber may under an embodiment travel from the interior space 522 of the rim 108 to the exit point 530 through a third portion. The third portion may comprise any path through the apparatus base and/or apparatus tank as long as the chamber moves air through a continuous enclosure without interfering with operation of the tank or base in (i) holding water, (ii) introducing water into the apparatus bowl, and/or (iii) removing or expelling water from the bowl. Under an embodiment, the air chamber 520 provides a continuous enclosure that vents air from each ventilation port 502, 504, 506, 508 to exit point 530.

An embodiment is described herein which locates the air chamber within the rim of a toilet apparatus. However, it should be understood that the air chamber may be located anywhere within the toilet apparatus so long as the chamber provides a continuous enclosure that vents air from ventilation ports to one or more exit points exiting the toilet apparatus.

FIG. 6 shows a front view of rim inner surface 138. Air port 502 allows communication of air between an interior of the bowl and air chamber 520. The port 502 and air chamber 520 reside above the water chamber 614 within apparatus bowl. Port 502 is exemplary of ports 504, 506, 508 which exist in similar configurations along the inner surface 138 of rim 108.

FIG. 7 shows one configuration of the ventilation system piped through a wall into an attic through a fan and out the roof, under an embodiment. FIG. 7 shows the apparatus base 712, the apparatus rim 714, and the apparatus tank 716. The water inlet 718 is attached to a water source to provide water to the apparatus 700. The air chamber (FIG. 5, 522) connects to a ventilation pipe at exit point 530. The pipe 730 may then connect to pipe 732 which extends upward inside a stud wall 722. An exhaust fan housing 724 rests upon a ceiling joist 726 and just below roof line 728. The exhaust fan inside the housing operates to move air from the chamber 520 in the apparatus through ventilation pipe 730, and then upward through ventilation pipe 732. The exhaust fan 724 then vents air out of the entire housing structure through ventilation pipe 734.

FIG. 7 shows an electrical switch 750 located on the wall behind the toilet. The switch may of course be located anywhere within the room containing the toilet or elsewhere in a corresponding building, house, or structure. The switch may control the exhaust fan and ventilation system in general.
